Abstract

A touch panel (4) and an operation part (30) are provided on display means (2). A permanent magnet (52) is mounted on a push button (32), and a magnetic metal plate (58) is mounted on a support frame (36). When the push button (32) starts to be pushed down toward the touch panel (4), the push button (32) moves toward the touch panel (4) against magnetic attractive force of the permanent magnet (52) and the magnetic metal plate (58), and an operation forward end part (46) operates a touch switch. Stroke feeling results from this movement. Further, the aforementioned magnetic attractive force abruptly reduces in an initial period of this movement, and an operator of the push button can attain click feeling. Since the stroke feeling and the click feeling are caused in the operation of the push button (32), operability is improved while making the best use of such an advantage that the touch panel (4) is of a thin type.

Description

The display unit of thin switch and belt switch

The present invention relates to for example be used for the thin switch of aspects such as factory automation instrument (FA instrument), automatic vending machine, automatic machine, information equipment, household electrical appliance, medical care precess instrument, and the display unit of using the belt switch of thin switch.

Touch pad is typical slim switch.Touch pad in brief, is a kind of tabular switch that has at least one switch portion and can operate under the depression stroke of this switch portion is almost nil, or has at least one through touching the tabular switch of pushing with regard to exercisable switch portion.

Touch pad has following various: 1. resistance membrane type (this transparency electrode formula that is also referred to as, down together), be two very little relative transparency electrodes are set between two transparent thin boards at interval and form, 2. photoelectric type, being that the light that will be sent by light-emitting component waits blocking or decay, 3. ultrasonic type with finger before entering photodetector, is that the ultrasonic wave that will be sent by ultrasonic oscillation element waits blocking or decay etc. with finger before entering vibration detecting element.

Touch pad 4 shown in Figure 1 is the resistance membrane type, in brief, be between transparent thin board, be provided with at least one from the outside gently (being that stroke is almost nil) one press the switch portion that can connect.In detail, being constructed as follows of this touch pad 4: on transparent thin board 6, be placed with a transparency electrode 8, stack a transparent thin board with a plurality of peristomes 12 thereon, have the transparent thin board 16 of transparency electrode 18 topmost below being. Transparency electrode 8 and 18 can be a plurality of mutually perpendicular strip shaped electric poles; Perhaps a side electrode as transparency electrode 18, is a plurality of electrodes; And another electrode is common electrodes as transparency electrode 8.Two transparent thin boards 6 and 16, since very thin, so have flexible.But tool is not flexible can yet for following transparent thin board 6.

Form switch portion 4a at each peristome 12 place, in this example, when pressing desired peristome 12 from transparent thin board 16 1 sides are light, deflections take place in the transparent thin board 16 of part in compression and transparency electrode 18, and transparency electrode 18 contacts to form by peristome 12 and following transparency electrode 8 and is electrically connected.But the size of each switch portion 4a, shape, number etc. are arbitrarily, and be in addition, also that a plurality of P cock 4a of portion are in parallel and use as integrated switch electric sometimes.

This touch pad 4, for example as shown in Figure 2, can be by it being stacked and placed on the display panel that constitutes belt switch on the display panel 2 with information display function.This display panel that has switch for example discloses in Japan Patent utility model 61, No. 723 (1986).Display panel 2 is normally used liquid crystal display.

Display panel 2 generally as shown in Figure 3, forms a viewing area 2a nearby in the bottom of the switch portion 4a of touch pad 4, wherein shows the operation selectable content of utilizing this switch portion 4a, as the control content of FA instrument, the destination of automatic machine etc.This facilitates selects and operates desired switch portion 4a.

Above-mentioned touch pad 4 has the advantage as thin as a wafer that gross thickness has only 1mm at most, but conversely, almost nilly (be approximately 0.1～0.2mm) specifically because the stroke of depress switch 4a is minimum, people's finger sense can't be discovered its displacement, thereby produces the problem of the what is called " stroke sense " of having no way of obtaining the 4a of console switch portion.The stroke sense claims " operation sense " again.

As can not get the stroke sense, operating personnel can since the what is called that can not get the 4a of console switch portion in sense and uneasiness, although switch portion 4a has connected, also can be repeatedly need not compress switch firmly.Just can not get the stroke sense when especially being with gloves fully.

Under the situation of above-mentioned only formula and ultrasonic type touch pad,, can not get the stroke sense fully because its operation only is finger to be contacted (being that depression stroke is zero) with its surface.

Be the problem of this shortage stroke sense that solves touch pad, proposed the display panel of belt switch as shown in Figure 4.This technology, for example,, open in No. 857 (1994) at Japanese patent application JP-A-644.

The display panel of this belt switch is respectively arranged with switch element 20 on each viewing area 2a of above-mentioned the sort of display panel 2.

Each switch element 20 comprises shell 22, transparent press button 24, and with the switching mechanism 26 of this press button operation, and image guide 28.Switching mechanism 26 has electric terminal and makes this electric terminal and back-moving spring (all omitting not shown among the figure) that press button 24 resets.Image guide 28 can be shown in the displaying contents of display panel 2 the respectively upper surface of this image guide 28 for the integrated element that the multifiber boundling becomes by it.Why image guide 28 will be set is because the setting of switching mechanism 26 strengthens the surface of display panel 2 and the distance between the press button 24 inevitably, need avoid showing and the shortcoming of inconvenience observation in the depths below press button 24 of the displaying contents on the display panel 2 before this.

The display panel of this belt switch, though owing to the depression stroke that can guarantee press button 24 to a certain extent obtains the stroke sense, but owing to adopting mechanical switch mechanism 26 to strengthen the thickness of switch element 20, because the event of above-mentioned reason must have image guide 28, but the problem below meanwhile producing.Promptly as described above, image guide 28 is to be formed by the multifiber boundling, but because the increase of the radical of optical fiber is limited, so figure matter is coarse, is difficult to show imperceptible part.And, from the light that send the upper surface of the optical fiber of composing images waveguide 28, the scope of its emission only be directly over about 70 °, be difficult to see clearly the displaying contents of display panel 2 from oblique direction.In addition, because the cost height of this image guide 28, the display panel overall cost of belt switch is also just high.

Situation when the following describes the display panel (console panel) that in console, uses this existing belt switch.

Compile on the used operating desk in the factory be useful on to the system that constitutes by machinery and equipment by personnel operate, move, discern, monitor, information necessary such as maintenance, operating desk occupies an important position as the man-machine interface between people and the machinery.

For that reason, turn round reliably, efficiently and safely in order to make system, wish operating desk be one to people close friend, and consider to provide from the human engineering angle and operate man-machine interface easily.

With regard to the operating desk of FA instrument system, be to system operation in the factory and operation by skilled operating personnel, but such as with regard to this system of the automatic machine in the railway station, the device that yes is operated as operating personnel by the ordinary people, thus to accomplish to use easily and good operability just extremely important.In addition, the console of automatic machine being used as broad sense herein.

In the operating desk of said system, from the people as operating personnel, it is necessary and indispensable human-machine interface function has two: one is that the people can discern this mechanical state, and another is that the people can operate on it.

That is, the residing state of system should show by the display on the operating desk, can be discerned and judged that the people then is elemental motion to the operation that this mechanical operating equipment carries out by the people shown information.

Therefore, in other words the so-called ease for use that improves operating desk, importantly improves operability and the identification of people to it, promptly improves demonstration property.

Yet shown information comprises the variable information that fix information that displaying contents is fixing and displaying contents can freely change on the operating desk, below with reference to Fig. 5 and Fig. 6 the example of this type of information display unit of present use is described.

Fig. 5 is the example with variable information display unit, is depicted as the current table top of used operating desk CP1 usually.

On table top, be provided with the display panel 2 of LCD as the information that shows FA instrument operating content etc.

LCD can be according to the setting of software program and is freely changed display frame, and this can be used as the example of the display panel that can show variable information.

Display panel 2 is provided with touch pad 4, and a plurality of switch 4a that arrange on touch pad 4 are relative with the viewing area of display panel 2 respectively superimposed and form display panel 2.

The touch pad 4 that is adopted in this conventional touch pad display unit TPD as mentioned above, can't obtain the stroke sense.Therefore, operating personnel can uneasiness have not been connected the situation of still repeatedly pushing although switch 4a can take place because pressing the feel of key.

In order to eliminate operating personnel's this uneasy sense, in the table top of as shown in Figure 6 operating desk CP2, when the LCD that adopts the demonstration variable information is as display panel DP, the concentrated console switch is set in addition, constitutes by being positioned at illumination press button switch I SW that locates around the LCD or the thin film switch MSW that is printed on typographic(al) mark on the surface etc. with famous brand.By these console switchs, the stroke sense in the time of can obtaining pressing operation.The function of these famous brands and typographic(al) mark is exactly the display unit of serving as fix information.

But, in this device that adopts LCD and concentrated switch simultaneously, at the another side that can obtain the stroke sense then is to make table top become big owing to be provided with the console switch group in addition around LCD, in addition, the fix information that can show in the concentrated console switch is limited, therefore, and in order to show the information of volume, must correspondingly increase the number of console switch with information content, and device will maximize.

In addition, owing to around LCD the concentrated console switch is set in addition, display frame and console switch must be compared and operate, this is generation misoperation easily just, causes the operability extreme difference.

Have, when the specification of operating desk changes, must correspondingly change table top with concentrated console switch number, the result has also strengthened cost in the number in increase man-hour.

As mentioned above, the touch panel display device in Fig. 5 example is owing to utilize the setting of software program can accomplish that the variation of display message, operation information shows.In the mini-mesa operation display device, might accomplish multiple demonstration, but because operating personnel do not have operation sense, and promptly operability is poor, it is thorough inadequately to have to consider from the viewpoint of ergonomics.

On the other hand, in example shown in Figure 6,, utilize these switches can improve personnel's operability greatly, can make the people when operation, obtain operation sense owing on the variable information display unit, disposed the concentrated switching device that is used for fixing information again.Yet, this will be around the variable information display unit the very many switches of configuration, the console area must be very big and cause maximization, is difficult to accomplish miniaturization.

As previously mentioned,, have only variable information or have only the situation of fix information rarely found as information shown on the operating desk, be mostly variable information and fix information simultaneously and the situation of depositing, the situation of various machines configurations is image pattern 6 illustrative operating table surface all substantially.

But, from table top on the whole, as shown in Figure 6, because the instrument that is used for showing the instrument of variable information and is used for fixing the display operation of information is subjected to certain restriction in configuration plane design, in addition, also entirely different at aspects such as designs, be difficult to make the people to feel clean and tidy, give a kind of mixed and disorderly impression of people, the success of on ergonomics, can not saying so.

The purpose of this invention is to provide a kind of not only had touch pad as thin as a wafer characteristics but also have the thin switch that knocks the stroke sense.

Another object of the present invention provides and a kind ofly no longer needs with image guide owing to adopted above-mentioned thin switch and can access the display unit of the belt switch that knocks the stroke sense.

A further object of the present invention provides a kind of display unit that the belt switch that " card clatter " (click) feel can be arranged when obtaining stroke sense (stroke).

A further object of the present invention provides a kind of display unit that can not cause operating the belt switch that display surface maximizes.

The switching device of object of the present invention for specified signal is switched.

Switching device according to the present invention has a touch pad, this touch pad have by stroke almost nil touch the soft-touch control that signal is switched, this switching device also comprises the operating portion that has at least one operating means, is used to carry out soft-touch control and operates and be arranged on this soft-touch control.

For this reason, each operating means includes one and is arranged at support on the soft-touch control, utilizes this support to be fixed on the reference position on the soft-touch control and can be by pressing to that soft-touch control makes it to break away from the reference position and press button that above-mentioned soft-touch control is operated and producing makes the resetting means of the reset response power that press button resets to the reference position by soft-touch control.

According to the present invention, when depressing the press button of operating portion, this press button moves and operates soft-touch control.In the present invention, owing to guarantee when depressing press button, can obtain depression stroke, thereby can obtain to make touch pad to accomplish as thin as a wafer characteristics, and can obtain clear and definite stroke sense simultaneously.

Switching device of the present invention is because ground must be provided with mechanical switch mechanism between press button and touch pad, so can make press button and touch pad lean on very closely.So the displaying contents of display panel can be shown on the very near press button of distance, and does not need image guide.

In most preferred embodiment of the present invention, utilize the magnetic device composite type device that resets.The combination of magnetic device can be used permanent magnet entirely, also can adopt the combination of permanent magnet and magnetic metal.

But " magnetic device " among the present invention (perhaps " magnetic ") is the general name that can produce the member of magnetic interaction, comprises permanent magnet and magnetic metal and magnetic resin (resin magnetic body) or the like.In addition, " magnetic metal " himself do not have the metal material of substantive spontaneous magnetization, promptly do not have a general name of metal, metallic compound (comprising metal oxide) and the alloy of remanent magnetization though be to have the character that produces magnetic interaction by magnetic response.

In most preferred embodiment of the present invention, can use 2 in resin, to sneak into the magnetic resin of magnetic as permanent magnet.

In a kind of form of the present invention, press button can slide along support body.In addition, press button can rotate in other forms of the present invention.

Preferably in the moving range of said reference position, the interval that reset force reduces is set to press button towards soft-touch control.In this case, when operating personnel when press button is depressed in the reference position, the reaction force that is produced by reset force can reduce in halfway.Can produce a kind of keystroke sense thus." keystroke sense " among the present invention not necessarily will accomplished by reducing above-mentioned reaction force with coughing up the sound of rattling away.

The present invention also provides the display unit of the belt switch that uses above-mentioned thin switch.The press button of this occasion adopts the material with transparency.But so-called " having the transparency " is that " transparent " reaches the general name of " translucent ".

Fig. 7 is that to have adopted touch pad be that resistance membrane type, press button are flatly moving type and can produce stroke and the part sectioned view of the embodiment of the display panel of the belt switch of the slim switch 80 of keystroke sense.Fig. 8 is the plane graph of display panel of the belt switch of Fig. 7.Fig. 9 is the profile of press button depressed state of the display panel of belt switch in the presentation graphs 7.

The structure of the display panel of belt switch among present embodiment and the embodiment that the following describes all is the stacked one slim switch 80 that has on the display panel 2 of information display function.

The canonical form of display panel 2 is the liquid crystal display that has by the variable Presentation Function of software program control, but also can be EL (electroluminescence) demonstration, Plasma Display, CRT, led array, and display message famous brand and liquid crystal shutter and be the luminous element of its illumination and the combination of reflecting plate etc., importantly preferably have information display function.In this occasion, when adopting magnet to make resetting means 50 described later, preferably use the display unit that is not subjected to its influence of magnetic field, as liquid crystal display, EL demonstration, Plasma Display etc., but when adopting spring to do to reset device 50, illustrated as described later, then there is not necessity of above-mentioned worry, even adopt CRT not have any problem yet.

In the display panel 2 of present embodiment, near the bottom of switch portion 4a on the touch pad 4 that constitutes slim switch 80, be formed with viewing area 2a and be used to show by the selected content of the operation of each switch portion 4a.So the selection of desired switch portion 4a and operation all are easy to.

Slim switch 80 comprises resistance membrane type touch pad 4 and at least one operating portion 30, resistance membrane type touch pad 4 is made of at least one 4a of transparent switch portion that is stacked and placed on the display panel 2 and between transparent thin board, switch can be connected when gently pressing from the outside, and operating portion 30 is arranged on the switch portion 4a of this touch pad 4.Touch pad 4 wherein is the resistance membrane type, has identical structure with that shown in Figure 1.

Each operating portion 30 constitutes an operating means, has a transparent press button 32.This press button 32 when it is depressed, is operated this switch portion 4a by switch portion 4a corresponding in the touch pad 4 is touched depressing removable certain stroke on the direction.Say in particular, show to, press button 32 integral body as arrow A in the present embodiment to retreat through certain stroke, depress the switch portion 4a corresponding and connect switch with touch pad 4 at the direction upper edge straight line of depressing.In addition, each operating portion 30 include near the edge part that is arranged at above-mentioned press button 32 respectively and produce the resetting means 50 be added on the reset force on the press button, guiding press button 32 is made up and down straight-line support 36 and is prevented the auxiliary section 40 that press button 32 is deviate near the edge that is arranged at press button 32 and in the position of regulation press button 32.

The flat shape of the viewing area 2a of display panel 2, the switch portion 4a of touch pad 4 and press button 32 is arbitrarily, but in the present embodiment, as an example, the viewing area 2a of display panel is a quadrangle, and the switch portion 4a of the touch pad 4 corresponding with it and viewing area 2a also are the quadrangles of similar size.This is identical with shape shown in Figure 3.In addition, correspondingly press button 32 and switch portion 4a also are the quadrangles (referring to Fig. 8) of similar size.But, the switch portion 4a of touch pad 4 not necessarily will be in the whole district on the viewing area 2a of display panel 2 or the whole district of press button 32 belows, bottom line is positioned at the position that near utilize press button 32 top of viewing area 2a of display panel 2 or be attached thereto member can operate and gets final product.In other embodiments herewith.

The structure of auxiliary section 40 is worked in coordination the extension 38 of the limit portion 34 of press button 32 and support 36 and is prevented that press button 32 from deviating from the present embodiment.

Resetting means 50 has utilized the repulsion between the permanent magnet and the combination of gravitation in the present embodiment, within the limit of press button 32 one 34, be provided with the movable side magnetic 52 of magnetic pole for laying up and down, within the base of support 36, position when being in press button 32 and being depressed corresponding to movable side magnetic 52, inside and outside relatively but up and down only part relatively be provided with fixation side magnetic 54, but its pole polarity is just laid up and down on the contrary with movable side magnetic 52.

This position of 52 and 54 relation of two magnetic is described in detail in detail below, and the position on two magnetics 52 and 54 its planes is inside and outside fully relative as shown in Figure 8.But then as shown in Figure 9, even be depressed 32 liang of magnetics 52 of press button and 54 also not exclusively just relative, movable side magnetic 52 being positioned at that the position of upwards staggering stops relatively on above-below direction.This point as following detailed description, is in order to prevent that two magnetics 52 and 54 from making press button 32 upwards not reset owing to attracting each other.

Two magnetics 52 and 54 are permanent magnet.Its magnetic pole also can be with fully opposite shown in the legend.In addition, two magnetics 52 and 54 can all be arranged more than one (specifically can be 2 or 4) as shown in Figure 8, as also can all arranging one for ring-type.Ringshaped magnet can be by magnetic being sneaked in the resin and method manufacturings such as shaping.In addition, two magnetics 52 and 54 can be different with Fig. 7 example, also can each some by in press button 32 and the support 36 to exposing outside.This point is like this too in other embodiments.

It is various that two magnetics are had at the relative device in above-below direction top, and pad 56 used among Fig. 7 is the one example.Other examples are stated as follows.

In the embodiment of Fig. 7, the below of press button 32 limit portions 34 is provided with the annular shim 56 of restriction press button 32 drafts.These pad 56 double positioning of components of useing the corresponding switch portion 4a of touch pad 4 as can move up and down.Though but be to move up and down, as long as its movable degree can make the switch portion 4a break-make of touch pad 4.As previously mentioned, the operational stroke of touch pad 4 switch portion 4a is almost nil, and the integral thickness of touch pad 4 also has only about 1mm, so movable also just enough apart from reaching this degree.

The following describes the working condition of embodiment among Fig. 7.Usually, because two magnetics 52 and 54 are that opposite pole is relative, the two poles of the earth gonosome 52 and 54 can be pressed to the top with press button 32 because of the repulsion effect.But owing to there is auxiliary section 40 to exist, press button 32 can not eject.

If the repulsion that resists between two magnetics 52,54 is pressed to the below with press button 32, then whole press button 32 is pressed down by support 36 guidings, is caught by pad 56, the corresponding switch portion 4a of touch pad 4 can be depressed by this pad 56 to make it to connect.The state of this moment as shown in Figure 9.

In this case, if depress press button 32, then when beginning, because the distance between two magnetics 52,54 diminishes, repulsion increases, but when pressing a certain scope (more than being pressed down to a certain degree), just can understand referring to Fig. 9, because the opposite pole of two magnetics 52,54 is approaching, gravitation begins to work, and makes so the repulsion between two magnetics 52,54 sharply reduces to depress that action lightens and even as easy as rolling off a log.

Like this, the action that sharply lightens in the middle of when press button 32 is depressed or feel to be exactly wink innervation or keystroke sense, as have this sensation, just can make operating personnel obtain the sensation that switching manipulation has been finished surely, thereby further improve the operation sense of switch.In addition, press button 32 sharply lightens when depressing and can make the certain complete operation of switch portion 4a that makes touch pad 4 by press button 32.In other words, promptly press button 32 can not stop in depressing process midway, thereby makes the operation of touch pad 4 more reliable.

But, though press button 32 is pressed down to foot, can be fully just in time not relative owing to be provided with pad 56, two magnetics 52,54, also repulsion can residually be arranged between two magnetics 52,54.This repulsion for example easily by changing the methods such as height of pad 56, is adjusted.

Therefore, if stop to press down press button 32, press button 32 can reset because being subjected to the repulsion effect of 52,54 of two magnetics and be blocked by auxiliary section 40.In addition, the switch portion 4a of touch pad 4 is resetted by the effect of itself power and switch is disconnected.So return to the state of Fig. 7.

Represent more in detail to this variation of reset force among Figure 10.The displacement D of position (" reference position " or " position of readiness ") the beginning press button 32 of Fig. 7 of the state of not depressing from press button 32 increase of starting from scratch after reset force F increases suddenly, reduces in interval Δ D.The mobile threshold value T of press button 32 is in the present embodiment by pad 56 regulations.Because the variation of reset force F comprises this interval Δ D, so can obtain the keystroke sense.Where can both reset for no matter press button 32 is in, reset force F whole interval O～T be on the occasion of.

Owing to can guarantee the depression stroke of press button 32 in above-mentioned slim switch 80, the type as thin as a wafer of touch pad changes into and is possible, can also obtain clear and definite keystroke sense in these characteristics of generation.Its result can obtain clear and definite feel and feel at ease for operating personnel when depress switch portion.As mentioned above, the stroke of this press button 32 (gauge of Figure 10 is apart from the size of T), in the occasion of present embodiment, by the distance decision between the upper surface of press button 32 lower surfaces and pad 56, for example more than 0. mm just are enough to obtain enough stroke senses to about 2.0mm.

In the occasion of present embodiment, as previously mentioned, outside the stroke sense, also can obtain the keystroke sense, thereby when improving operation sense more, the operation of switch is also more reliable.

In addition, the display panel of above-mentioned belt switch is will adopt the above-mentioned slim switch 80 of touch pad 4 to be stacked and placed on the display panel 2 and constitute, owing to mechanical spring mechanism must be set in existing example as shown in Figure 4 between press button 32 and display panel 2, the spacing of press button 32 and display panel 2 can be very little.For example, when the stroke of supposing press button 32 was approximately 0.5mm, the height of pad 56 was 2mm, since minimum 1mm that has an appointment of thickness of touch pad 4, thus the distance between the lower surface of press button 32 and display panel 2 upper surfaces, even when press button 32 is not depressed, also can be very little, be about 3.5mm at the most.Because the displaying contents of display panel 2 is to show apart from the very near part in press button 32 bottoms, so do not need in as shown in Figure 4 the existing example image guide to be set like that.As a result, it is coarse that the displaying contents of display panel 2 can not become, and can see the qualitative picture of display panel 2 self.In addition, because do not use the image guide of limits vision angle, also can know the displaying contents of seeing display panel 2 from oblique.In addition also since do not need high price because of image guide, also just no longer need complicated switching mechanism, structure becomes simply, thereby can reduce the cost of the display panel of belt switch.Except that can obtaining the stroke sense during press button 32, and also can obtain the keystroke sense in the present embodiment in operation.

In addition, under the present embodiment situation, touch pad 4 and press button 32 are in order all to get as previously mentioned as transparent with display panel 2 combinations, but, difference according to displaying contents of display panel 2 etc., also not necessarily leave no choice but transparent can not, translucent also passable, main a bit is as long as luminous energy sees through just passable from display panel 2.Promptly in this case, press button 32 should have the transparency.With other embodiment of display panel combination in also be like this.

In addition, above-mentioned slim switch 80 also can not be stacked and placed on the display panel 2 and use, for example slim switch 80 and display panel 2 used separately respectively or use and also can with other instrument combination, at this moment, because do not require the light transmission that allows following display panel 2 send, so it is transparent or semitransparent that touch pad 3 and press button 32 need not be made, even opaquely also can.At this moment, in order to discern press button 32, can be on the note of the surface of press button 32, engrave or stick literal or mark.Among other embodiment herewith.

But, the also available transparent thin board of pad 56, if when as in the present embodiment, doing circlewise, because the switch portion 4a of touch pad 4 can only be pressed onto the inconspicuous part in 2a edge, viewing area of display panel 2, even so injure touch pad 4 owing to depress press button 32 accidentally, because be unshowy part, also can prevent because long-time the use causes the displaying contents of display panel 2 not see Chu.

Also can in the limit of press button 32 one at least one outstanding leg 42 be set downwards and replace above-mentioned pad 56 as illustrated among Figure 11, this leg 42 can be pressed on the corresponding switch portion 4a of touch pad 4.This leg 42 also can be done leg circlewise, or can be on press button 32 lower surfaces a plurality of positions, such as, dispose a plurality of legs in four bights.Because a plurality of legs 42 can be pressed onto the 4a of target switch portion of touch pad 4 reliably with very little power, the reliability of switching manipulation is very high.

Such leg 42 is set also can reaches effect and the effect same with pad 56.Also promptly when press button 32 is depressed, movable side magnetic 52 is just partly relative on above-below direction with fixation side magnetic 54, can prevent that press button 32 from can not reset upward.In addition, also can prevent touch plate 4 not the scar at showy place cause the displaying contents of display panel 2 not see Chu.And, because leg 42 can form one with press button, to compare with the occasion that pad 56 is set, component number reduces, and is attached thereto to be, assembles more simply, and cost is reduced more.

Even above-mentioned pad 56 and leg 42 are not set, also can be by movable side magnetic not being placed in lower surface place near press button 32, but place it in place, press button 32 tops, just part was relative on above-below direction with fixation side magnetic 54 for movable side magnetic 52 when press button 32 was depressed.

In addition, with the situation of display panel 2 combination under, in the inside of press button 32 or the lower surface place as shown in figure 12 example protruding elegant mirror 70 is set also can.Usually make the viewing area 2 of display panel 2 be positioned within the focal length of these convex lens 70 this moment.If such convex lens 70 are set, convex lens 70 can amplify the displaying contents of the display panel 2 of its below, in other words, can make it come-up and show, so the displaying contents of display panel 2 is easier sees clearly.

If not the space that convex lens 70 is placed between press button 32 and the display panel 2, but place it on the inside or lower surface of press button 32, then can not occupy additional space,, can prevent that the integral thickness of the display panel of belt switch from increasing yet even convex lens 70 are set.

The lower surface of convex lens 70 also can become the plane as example among Figure 14, but as concave slightly as illustrated in making among Figure 12, owing to have only the limit portion of press button 32 to be pressed onto on the following touch pad 4, strength just can be concentrated and guarantees to finish and depress operation on the 4a of target switch portion on the touch pad 4, can avoid the unshowy place of touch pad 4 injured simultaneously.

Certainly, if when touch pad 4 injured things can not constitute problem, also can for example convex lens 70 be made with its part from the outstanding downwards shape of press button 32 lower surfaces as illustration among Figure 13.So, because these convex lens 70 have been born the effect of aforementioned pad 56 and leg 42, so they can be omitted.

Press button 32 with above-mentioned this convex lens 70 for example can adopt the way of dual mould-formings or embedding to make with the convex lens of being made by the relative big transparent resin of refractive index 70 by the press button 32 made by the relatively little transparent resin of refractive index.

Above-mentioned leg 42 and convex lens 70 also applicable to following other embodiment that will illustrate, also can reach as hereinbefore effect and effect.Convex lens 70 also can be the Fresnel Lenses with convex lens effect.In addition, in the example of Figure 11 to Figure 13, the situation of laying movable side magnetic 52 in press button 32 is arranged also, but in diagram, movable side magnetic 52 is omitted.

In addition, to the surface of press button 32 preferably disappear reflection processing and antimicrobial coating.This point, like this too in the following embodiments.

And for example shown in the double dot dash line among Fig. 7, the most handy flexible transparent thin slice 74 to major general's press button 32 and and on every side the upper surface in the people crack 72 between the press button 32 cover, simpler way is that the upper surface with the parallel a plurality of operating portions 30 that are provided with is all covered.

If handle like this, just can prevent the globule and dust from the space 72 enter and be attached to touch pad 4 the surface, prevent that the globule from spreading between touch pad 4 and display panel 2, thereby can avoid the demonstration of display panel 2 to thicken unclear.Certainly, because resistance membrane type touch pad 4 has water-proof function usually, usually can be owing to the globule causes functional fault.In addition, if under the many environment of dust such as factory, use, also clean the surface of press button 32 easily.Therefore, being provided with of thin slice 74 can be realized waterproof and dustproof construction very simply.

The material of above-mentioned thin slice 74 is such as being transparent silicon rubber or clear PET (polyethylene terephthalate).The former is flexible very big, so thin slice 74 can be made simple writing board shape.Therefore the latter's is flexible slightly little, and the stroke best and press button 32 of the part on press button 32 is piled thickly accordingly, promptly carries out protruding bloated processing so that press button 32 these parts are easy to depress.

＜the 2 embodiment 〉

The following describes other embodiment.But, omitted the difference of main only explanation and front embodiment with the repeat specification of the embodiment same section of front.

Figure 15 is for adopting resistance membrane type touch pad, flatly moving type press button and can producing the stroke sense and the part sectioned view of another embodiment of the display panel of the belt switch of the slim switch 80 of keystroke sense.

In the embodiment of Figure 15, resetting means utilizes the polarity of permanent magnet and magnetic holding plate, magnetic holding plate 58 is set as fixation side magnetic 54 on the top of support 36, in the limit of press button portion and be to have a movable side magnetic 52 to attract each other with magnetic holding plate 58 in the lower portion of this magnetic holding plate 58 respectively.Magnetic holding plate is made by the ferromagnetism metal, for example can be iron plate.But magnetic holding plate 58 is in non-spontaneous magnetization state (promptly not being with remanent magnetism).When making magnetic holding plate 58 produce induced magnetizations, then between movable side magnetic 52 and magnetic holding plate 58, producing magnetic interaction by the magnetic field of movable side magnetic 52.

In the present embodiment, movable side magnetic 52 and magnetic holding plate 58 attract when flat strongly, and when press button 32 is depressed, if power that need not be certain during beginning then press button 32 can't be depressed, but after press button 32 is depressed some a little, gravitation between movable side magnetic 52 and the magnetic holding plate 58 sharply dies down, and therefore depresses and becomes brisk rapidly, promptly also can obtain the keystroke sense outside the stroke sense.Depress when stopping, because the effect of the gravitation between movable side magnetic 52 and the fixation side magnetic 58, press button 32 resets.

But in the present embodiment, owing to leg 42 1 base parts among the pad 56 that does not need the embodiment among Fig. 7 or aftermentioned Figure 11, so the thickness of slim switch 80 just can correspondingly reduce, simultaneously the distance between the upper surface of the lower surface of press button 32 and display panel 2 can diminish, thereby the displaying contents of display panel 2 is easier sees clearly.In addition, because magnet only uses movable side magnetic 52 to get final product, fixation side magnet can be with cheap magnetic holding plate 58, so cost just can correspondingly reduce.

The situation of change of the reset force in the present embodiment as shown in figure 16, the reset force F that is produced by magnetic attraction along with the increase of press button 32 displacement D is non-linear and reduces.Under the situation of present embodiment, the whole interval of O～T of reset force F particularly sharply reduces at the incipient stage of displacement reset force F for reducing the interval.But, because the embodiment of present embodiment and Fig. 7 does not adopt pad 56 equally, so the position when mobile gauge T is exactly press button 32 arrival touch pads 4.

In addition, present embodiment also has an advantage to be because the magnetic circuit that magnetic holding plate 58 produces is closed, so very weak by the outside leakage field of movable side magnetic 52 generations.

＜the 10 embodiment 〉

Figure 28 is the part sectioned view of the embodiment of the display panel of the belt switch of the slim switch 80 of employing resistance membrane type touch pad.Figure 29 is the plane graph of the press button among Figure 28.

The formation of the slim switch 80 in the present embodiment comprises by being stacked and placed on the display panel 2 and by the touch pad 4 that is arranged at the above-mentioned the sort of resistance membrane type that at least one transparent switch portion 4a that can connect from the light pressure in outside between transparent thin board forms and be arranged at least one operating portion 30 on the switch portion 4a of this touch pad 4.

The formation of each operating portion 30 comprises a transparent press button 32, a projection 45 of using as fulcrum is arranged on the lower surface of this press button 32, end points with this projection 45 is that fulcrum can rotate certain stroke at direction of exerting pressure along direction shown in the arrow B, and the 4a of respective switch portion that utilizes operative end 46 that separate with projection 45 with fulcrum and that be positioned at lower surface to be pressed on touch pad 4 just can make switch connection; Also comprise and be positioned on the lower surface near press button 32 is applied reset force and produces the resetting means 50 of the keystroke sense simultaneously end that the fulcrum of press button 32 therewith separates with projection 45.In addition, each operating portion 30, in this embodiment, also include near being arranged at outside press button 32 ends support 36 and thus support 36 or the member that is attached thereto with press button 32 ends or the member that links to each other cooperatively interact and prevent the auxiliary section 40 that press button 32 comes off.

Near display panel 2 upper press buttons 32 bottoms, form the viewing area 2a that shows by the selected content of operation of press button 32 in the present embodiment.Thereby select and operate desired press button 32 to be easy to.

The viewing area 2a of display panel 2 and the flat shape of press button 32 can be arbitrarily, in the present embodiment as an example, the viewing area 2a of display panel 2 is decided to be quadrangle, and correspondingly press button 32 also is the quadrangle (with reference to Figure 29) with viewing area 2a same size.

Fulcrum projection 45, in the present embodiment, from Figure 28, also can see, be arranged near the end of press button 32, more specifically say so on same press button 32 lower surface on one side, edge respectively this limit is elongated strip, and near the end of opposite side, more specifically saying so is provided with aforesaid end 46 on the lower surface of fulcrum with one side of the opposition side of projection 45.The fulcrum that is press button 32 is exactly to be used for the operative end 46 that switch portion 4a to touch pad 4 exerts pressure and make it to connect with the opposition side of projection 45 lower surface on one side.

In addition, in the present embodiment, this operative end 46 is provided with downwards the outstanding switch portion 4a that is used for touch pad 4 and exerts pressure the operation of operation with projection 47.In the present embodiment, this operation is hemispherical with projection 47, has only one, but this operation is not limited with the shape and the number of projection 47.For example, one side more than one operation can be arranged in a line along aforesaid with projection 47, also can line up triangle, quadrangle or circle.In addition, operation selects for use cylindricality also passable with the shape of projection 47, and is also more passable than the strip that cylindricality width is wideer.This operation also can be opened also at aforesaid flatly moving type with projection 47 and is provided with among the embodiment.

The switch portion 4a of touch pad 4 can be arranged on this operation below with projection 47, if setting operation is not with projection 47, just is arranged on the below of aforesaid operations end 46.This point is like this equally to other embodiment that below will illustrate.

Also have,,, also can be arranged on the switch portion if this switch portion is not used though the fulcrum of press button 32 is arranged on the non-switch portion on the touch pad 4 usually with projection 45.That yes is inequality for the above-mentioned switch portion 4a of the operand of this obsolete switch portion and press button 32.

Though be not that above-mentioned this operation projection 47 must be set on the operative end 46 of press button 32, if but be provided with, utilize this operation projection 47, the purpose switch portion 4a that can use less power to finish reliably touch pad 4 depresses operation, so can improve reliability.

In the present embodiment, near the top of the upper surface operative end 46 of press button 32, be provided with as a mark of the mark of depressing operation with projection 48.Though this mark is optional with projection 48, if be provided with, but then be convenient to see clearly the operation part of press button 32, make press button 32 to depress operation easier.

In addition, above-mentioned this operation projection 47 and mark projection 48 can certainly be set in the embodiment beyond Figure 28.In addition, in all embodiment, for ease of diagram, the operative end 46 of press button 32 all is shown in the left side on figure, and the mode that places downside or operator's one side to dispose slim switch 80 operative end 46 in actual the use can be improved operability.

In the present embodiment, resetting means 50 be arranged at the fulcrum of press button 32 end with projection 45 relative sides near, also promptly be arranged at and the limit portion of 46 the same sides, aforesaid operations end near.In the present embodiment, this resetting means 50 is to utilize the gravitation between permanent magnet and magnetic to constitute as the magnetic holding plate 58 of fixation side magnetic 54 and the fulcrum that the is arranged at press button 32 movable side magnetic 52 with this magnetic holding plate 58 of attraction of the lower portion of the end of a relative side of projection 45 and above-mentioned magnetic holding plate 58 by being arranged at support 36 tops.Magnetic holding plate 58 is by the ferromagnetism metal, and for example iron plate is made.

Movable side magnetic 52 for example can be a permanent magnet.This movable side magnetic 52 also can be different with the example that Figure 28 is drawn, and its part is by exposing in the press button 32.Also but some exposes from support 36 fixation side magnetic 54 described later.These 2 like this too in other embodiments.

An example of movable side magnetic 52 planar configuration shown in Figure 29.This movable side magnetic 52 can be arranged at the whole limit portion of fulcrum with the opposite side of projection 45, also can as this example it be arranged at limit portion mid portion, perhaps also can be arranged near this limit both side ends.Take which kind of mode all can decide by essential suction between this movable side magnetic 52 and the magnetic holding plate 58 etc.But, in either case, the magnetic holding plate 58 of object is set above this movable side magnetic 52 all.

The structure of auxiliary section 40 is that the end 34 of press button 32 and the extension 38 of support 36 cooperatively interact in the present embodiment, prevents that press button 32 from deviating from.But, also can not establish extension 38 and directly magnetic holding plate 58 is set and makes it to constitute auxiliary section 40 with the end 34 of press button 32 in the upper end of support 36.

Acting as of support 36 supported above-mentioned magnetic holding plate 58 or fixation side magnetic 54 described later and formed auxiliary section 70 etc., it can be arranged at around the press button 32, or the relative both sides of press button 32, say that more specifically only to be arranged on fulcrum also passable with the outside of the limit portion of projection 45 sides and relative side portion.

The following describes the work of Figure 28 embodiment.At ordinary times, movable side magnetic 52 attracts because of the brute force that is subjected to magnetic holding plate 58, and operative end 46 1 sides of press button 32 are lifted under this graviational interaction.But because the existence of auxiliary section 40, press button 32 can not deviate from (ejection).

If the gravitation of the movable side magnetic 52 of resistance, depress press button 32, this press button 32 will be pressed the certain stroke of direction shown in the arrow B (counterclockwise of more specifically saying so) rotation with projection 45 for propping up with fulcrum, and its operation will be pressed on the switch portion 4a of touch pad 4 and make switch connection with projection 47.

In this case, the brute force that movable side magnetic 52 is subjected to magnetic holding plate 58 attracts, therefore, if the brute force that press button 32 is subjected to a certain degree when beginning is depressed, press button 32 can not rotate, rotate a little but work as press button 32, the gravitation of movable 52 pairs of magnetic holding plates 58 of side magnetic just sharply weakens, thereby can obtain the keystroke sense.

After press button 32 stopped to depress, because the graviational interaction of movable 52 pairs of magnetic holding plates 58 of side magnetic, press button 32 resetted.In addition, the switch portion 4a of touch pad 4 also resets by relying on oneself and disconnects.The effect that obtains stroke sense and keystroke sense is identical with the translation switch device of Fig. 7 etc.Situation of change with the mobile reset force of press button 32 is identical with the diagram of Figure 16.

In addition, in the present embodiment, be movable side magnetic 52 use magnetic just can, fixation side then can be used the magnetic holding plate 58 more cheap than magnet, so also uses the embodiment of magnet to compare cost with fixation side and can reduce.Also have, its another advantage is to form closed magnetic circuit by magnetic holding plate 58, and movably the outside stray field of side magnetic 52 is very weak.

The shape that fulcrum is made outside the strip shown in Figure 29 with projection 45 is also passable.For example, the fulcrum of a plurality of point-like or short strip shape also can form a line with projection 45.

In addition, as shown in figure 30, also can be near 32 1 ends of press button, more specifically say so near these both sides, end, the fulcrum that two short strip shapes are set separated from each other makes it to be in row with projection 45,45, and the position between near two fulcrum usefulness projection 45,45 the end of opposite side also promptly is provided with aforementioned operation projection 47 near the centre, end of this opposite side.

The switch portion 4a of touch pad 4 is that the cross part by the transparency electrode 8 and 18 (with reference to Fig. 1) of mutually orthogonal forms usually shown in Figure 30 section line, use the structure and the configuration as above-mentioned of projection 47 with projection 45 and operation as fulcrum, then when being arranged side by side the operating portion 30 of a plurality of same structures, since the distance between the operand switch portion 4a of the press button 32 that the fulcrum of a press button 32 is adjacent with projection 45 than only adopt a support with the occasion of projection 45 for greatly, so even the integration density of operating portion 30 is very high, the misoperation possibility that mistake is connected the 4a of adjacent switch portion is also much smaller.

In addition, above-mentioned fulcrum with projection 45 also not necessarily leave no choice but to be provided with press button 32 the end can not, also can be arranged on the both sides of press button 32 middle bodies.Be located at both sides and be in order to avoid middle body, publicly just make fulcrum can not hinder the demonstration of seeing display panel 2 clearly with projection 45.Near the aforementioned operation end 46 that a switch portion 4a who is used for depressible touch pad 4 is arranged the end that separates with projection 45 with this fulcrum of press button 32 for this reason.Resetting means 50 generally is located at therewith operative end 46 with near the side end, but is located at the also passable to side end of this operative end 46.

In addition, when making up with display panel 2, on the inside or lower surface of press button 32, for example as shown in figure 31, it is also passable that convex lens 70 are set.In this case, common viewing area 2a with display panel 2 is placed within the focal length of these convex lens.If this convex lens 70 are set, utilize these convex lens 70 displaying contents of the display panel 2 below it can be amplified, in other words can make to show come-up, thereby the displaying contents of display panel 2 can be seen clearlyer.

The combination of＜5-1A. and flatly moving type 〉

Figure 60 is for adopting photoelectric type touch pad, flatly moving type press button, and can producing the part sectioned view of embodiment of display panel of belt switch of the slim switch 80 of stroke sense and keystroke sense.

Slim switch 80 in the embodiment of this Figure 60 have with Figure 15 embodiment in a same operating portion 30 and a photoelectric type touch pad 314.

The formation of touch pad 314.With reference to Figure 61, comprise a plurality of light-emitting components 84 that send light 86 and accept this light 86 and open a plurality of photodetectors 90 that it are transformed to the signal of telecommunication that these elements are in the configuration and form rectangular light path 88 on the surface of substrate 82 and the space plane between the press button 32 relatively in length and breadth of the limit of substrate 82.Article two, the intersection point near zone of light path 88 forms switch portion 314a respectively.

Be respectively equipped with hole or the otch 39 that light 86 is passed through in the bottom of each support 36.But this part also can use transparent resin to make.

Substrate 82 for example is transparent or semitransparent glass substrate.But when replacing substrate 82 with the substrate that constitutes display panel 2 etc., substrate 82 can omit.

Each light-emitting component 84 for example is LED, semiconductor laser etc.Each photodetector 90 for example is photodiode, phototransistor etc.

The light 86 that each light-emitting component 84 is sent, as be infrared light, human eye be cannot see, and is very desirable, and visible light also can certainly.In addition, the light-emitting mode of each light-emitting component 84 can be continuous light-emitting mode, also can be the light-emitting mode (this light-emitting mode in turn also claims scan pattern) of taking turns that utilizes microcomputer etc.Microcomputers wherein etc. for example also can detect loop 92 as following illustrated being used for.

On each photodetector 90 on the direction in length and breadth, shown in Figure 61 in this example, be connected with and detect loop 92, thereby detect the position (coordinate) of the intersection point of the light path 88 that light quantity reduces, also promptly determine the switch portion 114a that is operated so that the signal from each photodetector 90 is responded.But this detection loop 92 also can not be attached to this touch pad 114, but utilizes a loop that is provided with in the instrument that is connected or utilize microcomputer etc.

In the past the near surface of this touch pad 314 as finger etc. near the time light can be covered and complete operation, but like this because not have the moving part depression stroke be zero, so can not get the stroke sense.In addition, at finger during, or do not make in several switch portion finger for the moment clear and in the middle of their, gesticulate (" giving directions operation ") etc. and all can cause misoperation inadvertently near the near surface of touch pad 314.

At this point, the structure in the present embodiment is for being light 86 is covered or to decay when press button 32 is depressed.Press button enters light path 88 when also promptly pressing a press button 32.When being opaque, it can cover light 86 fully at press button 32.At press button 32 when being transparent or semitransparent, though light can not be covered fully, but, there is press button 32 to enter in the light path 88 thereby can detect because refraction in press button 32 and decay etc. can make light quantity reduce and make the output signal level reduction that corresponding photodetector 90 is sent.Press button 32 when transparent or semitransparent in order to strengthen effect to the shading or the decay of light 86, the end face blacking that is positioned at the press button 32 of light path 88 can be made it opaque, also this end face can be carried out half-light processing and make light 86 scatterings or carry out mirror finish etc. light 86 is reflected.Perhaps, because movable side magnetic 52 is opaque, its position arrangement also can on light path 88.

Like this, different because can guarantee to depress the stroke sense of press button 32 in this slim switch 80 with the occasion of the original photoelectric type touch pad of independent use, can obtain clear and definite stroke sense.And when using this operating portion 30, as previously mentioned, also can obtain the keystroke sense.

In addition, when using original photoelectric type touch pad separately, if its surface has on foreign matter (as worm, dust etc.) falls, can occur owing to it covers light path the problem that misoperation takes place, and when using this slim switch 80, on press button 32, fall to going up foreign matters such as worm, dust and also can not produce misoperation, so its reliability height.

In addition, in the display panel of the belt switch of this embodiment, identical with the embodiment of front, distance between press button 32 and the display panel 2 can be reduced (for example being about 1～2mm), so the displaying contents of display panel 2 can show very nearby at distance press button 32, can not make the image guide that shows come-up even do not use, the displaying contents of display panel 2 also can come into plain view.

In addition, the operating portion 30 of matrix configuration and the number of light path 88 are not limited to 3 * 2 shown in Figure 61, can be m * n arbitrarily (m and n for greater than 1 integer), and concrete big I is determined according to purposes etc.

＜the 28 embodiment 〉

Figure 62 is for adopting photoelectric type touch pad, flatly moving type press button, and can producing the part sectioned view of embodiment of display panel of belt switch of the slim switch 80 of stroke sense and keystroke sense.

The slim switch 80 of embodiment in this Figure 62 be by with the embodiment of Figure 22 in identical operations portion 30 and with the embodiment of Figure 60 in identical photoelectric type touch pad 314 combine, can reach the front to the illustrated same action effect of this embodiment respectively.But to the operation of the switch portion 314a of touch pad 314, i.e. the blocking of light 86 or decay is to utilize leg set on the press button 32 42 to finish.

＜the 29 embodiment 〉

Figure 63 is the profile of another example of the display panel of the belt switch of employing photoelectric type touch pad, and Figure 64 is the display panel of the belt switch of Figure 63 and the plane graph that detecting circuit illustrates simultaneously.In addition, Figure 65 and Figure 66 are the partial enlarged drawing of these parts.

Optoelectronic switch 450 in this example has a plurality of transparent light guide bodies 452, and these light conductors 452 are configured to rectangular in the vicinity, outside, bottom of the two sides that intersect vertically of the press button 32 that constitutes each operating portion 30, centre and each press button 32 corresponding otch 454 that are provided with.Have two protuberances 456 outstanding to aforementioned transparent light guide body 452 from the aforementioned two sides that intersect vertically of each press button 32, these protuberances 456 are positioned within the otch 454 with these press button 32 corresponding light conductors 452 respectively.A plurality of light-emitting components 462 from an end of each light conductor 452 to wherein injecting light 86 respectively.In addition, a plurality of photodetectors 466 are accepted respectively to be transformed to the signal of telecommunication from the light 86 of light conductor 452 other ends ejaculation and with it.

In this example, each light conductor 452 is disposed within the bottom of the aforementioned guiding elements 432 that each operating portion 30 is cut apart in length and breadth and is positioned at from display panel 2 and upwards improves the position that a distance equals the stroke of press button 32.Configuration is during light conductor 452 like this, for example can be guiding elements 432 in light conductor 452 be carried out method realizations such as secondary mould-forming.When being disposed at light conductor 452 within the guiding elements 432, on guiding structure 432, the otch that tolerable protuberance 456 enters and can move up and down to be set in the place identical with otch 454.

Each light conductor 452 for example can be made by transparent plastic.Its section shape can be quadrangle, also can be circle.

To press button 32, shown in Figure 65, all near disposing each light conductor 452 in length and breadth.On the light conductor 452 each press button 32 respectively is provided with an otch 454 that is interrupted setting on this light conductor 452 in length and breadth at each.

Have on two sides that intersect vertically of close light conductor 452 configuration of each press button 32 two protuberances 456 outstanding and lay respectively at this press button 32 corresponding light conductors 452 on two otch 454 within.

Each protuberance 456, referring to Figure 66, its top is opaque 458 in this example, the bottom is a hyalomere 460.When press button 32 lifted, when promptly remaining in common state, hyalomere 460 was positioned within the otch 454, because this hyalomere is arranged, not only allowed but also helped light 86 by light conductor 452 by otch 454.When press button 32 was depressed, opaque 458 was positioned at otch 454, because this opaque 458, the light 86 by light conductor 452 is covered at otch 454 places be can't pass.

In addition, movable side magnetic 52 double opaque 458 of filling protuberance 456 also can.This needs only movable side magnetic 52 can be realized simply to protuberance 456 1 side shiftings or prolongation by Figure 66 as can be known.

Each light-emitting component 462 for example is LED, semiconductor laser etc.Each photodetector 466 for example is photodiode, phototransistor etc.The two is connected to the two ends of each light conductor 452.

The wavelength and the light emitting control mode of the light 86 that each light-emitting component 462 sends are identical with the occasion of Figure 60.The microcomputers that use with scan mode etc. for example also can be used for and constitute the detection loop 468 that the following describes.

On each photodetector 466 of arranging in length and breadth, in this example shown in Figure 64, be connected with and detect loop 468 so that the signal from each photodetector 466 is responded, thereby detect the place that light conductor 452 position of intersecting point (coordinate) are blocked, more specifically say to be exactly to determine the press button 32 depressed.But this detection loop 468 also can not be attached to the display panel of this belt switch, but utilizes loop or the microcomputer that is provided with in the instrument that display panel connected of this belt switch.

In addition, movable side magnetic 52 and light conductor 452 separate in the plane in Figure 65.Therefore, correctly say, light conductor 452 and protuberance 456 should not occur among Figure 63 of the section of movable side magnetic 52, just just that light conductor 452 and protuberance 456 is shown in Figure 63 for simplicity.In addition, in Figure 63, central authorities press button 32 shown in pointed 470 states of depressing.

The situation that can obtain stroke sense and keystroke sense in the display panel of this belt switch is identical with aforementioned other embodiment.In switch motion, when depressing press button 32, two protuberances 456 of this press button 32 light 86 will be passed through with corresponding two light conductors 452 in length and breadth of this press button 32 in otch 454 blockings.More specifically, as previously mentioned, opaque 458 of each protuberance 456 is within each otch 454, and this opaque 458 will be by light 86 blockings at this place.Therefore, and there is not light 86 to inject in two photodetectors 466 that light conductor 452 that light 86 is interdicted is connected, this two loops cut-out.Just can determine that according to this combination which press button 32 is depressed.

When pushing of press button 32 stopped, movable side magnetic 52 was subjected to fixation side magnetic 54 graviational interactions that press button 32 is resetted.After press button 32 resetted, the hyalomere 460 on these press button 32 protuberances 456 was positioned within light conductor 452 otch 454 and light 86 is recovered by this place.Therefore, in above-mentioned two photodetectors light 86 incidents are arranged, this two loop recovers to connect.

The structure of the display panel of this belt switch is that to make the light 86 that is sent by light-emitting component 462 be not to enter photodetector 466 at spatial transmission, but the inside by light conductor 452 is to light 86 channeling conducts and utilize 456 pairs of these light 86 of protuberance to block on the way to make it interrupted.When the occasion of light 86 at spatial transmission, in the space light 86 disperse increase, the decay of light 86 that can be mapped to photodetector 466 is very big, therefore, just misoperation might take place as the output that does not strengthen each light-emitting component 462.In addition, also may inject adjacent irrelevant photodetector 466 and misoperation takes place by a light-emitting component 462 luminous light 86.In contrast, when as present embodiment, being provided with light conductor 452, because light 86 is by its inner photodetector 466 that imports correspondence, so there is not the possibility of not injecting other adjacent photodetectors 466 and misoperation taking place.In addition, compare with the occasion in space divergence, light 86 decay that are mapped to photodetector 466 are very little, so the output of each light-emitting component 462 can reduce.

In addition, in the display panel of this belt switch, the incision of light conductor 452 be not singly be make opaque 458 turnover and will make it to take place by 86 blockings at this place interrupted, but also make light 86 by in put hyalomere 460 into otch 454 and carry out relaying by 460 pairs of light of hyalomere 86.In the occasion that hyalomere 460 does not enter otch 454, can disperse in the space at otch 454 place's light 86, thereby the ratio that enters the light 86 in the light conductor 452 once more can reduce.Also promptly the attenuation at otch 454 light 86 is big.In addition, can not say that the light of dispersing at otch 454 places 86 can not enter another extremely near otch 454 and produce misoperation.In contrast, if add hyalomere 460, owing to guided in this hyalomere 460 by the light 86 of otch 454, just very little in the ratio of space divergence.Also promptly in otch 454 attenuation of light 86 very little.In addition, also no longer there is the possibility that enters other light conductors 454 generation misoperations.

Like this,, remove when can eliminate the possibility of misoperation, also have the effect of the output that can reduce each light-emitting component 462 from two aspects owing to adopt light conductor 452 and hyalomere 460.

In addition, owing in the display panel of this belt switch, adopted optoelectronic switch, different with the display panel of original resistance membrane type belt switch, there is not the contact life problems.

In addition, with the transparency electrode that constitutes touch pad in the display panel of resistance membrane type belt switch is not that complete transparent this point is different, there is no need to be provided with the parts that the such optical transmission rate of transparency electrode is worsened in the press button 32 in the display panel of the belt switch of present embodiment, so the visibility spy of display frame is good.

＜the 30 embodiment 〉

Figure 67 is the sectional arrangement drawing according to the display unit of the belt switch of the embodiment that adopts leaf spring.Also be that otch 39 by support 36 passes through light 86 in this example, when press button 32 is depressed, by press button 32 with light 86 blockings.The light path design of light 86 is avoided leaf spring 62.The situation of another light 88 is identical therewith.

Yet, in each example that adopts the photoelectric type touch pad, a plurality of operating portions 30 are not necessarily non-on display panel 2, be configured to rectangular.For example, as shown in Figure 68, a plurality of operating portions 30 are gone up and are arranged in a direction (for example horizontal or vertical), with the corresponding respectively optoelectronic switch 450 that comprises light conductor 452, light-emitting component 90 and photodetector 84 that is provided with of each operating portion 30, wherein to make it break-make respectively by the protuberance 465 of its corresponding press button 32 also passable for the otch 454 of each light conductor 452.In addition, 450 1 of operating portion 30 and optoelectronic switches join one also passable.

Shown in Figure 68 example, lead the occasion that an operating portion 30 is set in million bodies 452 at one, opposite with previous embodiment, only depressing the just otch 454 by light conductor 452 of light in the press button 32.In this case, opposite with previous embodiment, hyalomere can be located at protuberance 456, and opaque portion is located at the bottom.This modification can be used for the embodiment of following rotary type press button too.

The combination of＜5-1B. and rotary type 〉

Figure 69 is the part sectioned view of the display panel of the belt switch of employing rotary type press button.In addition, Figure 70 is the partial plan layout of the press button among Figure 69.

Slim switch 80 in the embodiment of this Figure 69 has operating portion 30 and the photoelectric type touch pad 114 same with Figure 28 embodiment.

Equally with reference to Figure 71, touch pad 314 can be exported a plurality of light-emitting components 84 of light 86 and accept this light 86 and convert it to a plurality of photodetectors 90 of the signal of telecommunication to configuration over the ground in length and breadth in the one of the limit of substrate 82, and forms rectangular light path 88 in the space of 32 of the surface of substrate 82 and press buttons.Article two, just become each switch portion 314a near the intersection point of light path 88.

Vertically (above-below direction among Figure 70) light path 88 is positioned at the top of press button 32 operative end 46.This operative end 46 is along one of oblique cutting-out in this example, purpose be for the area that makes the operative end 46 that enters vertical light path 88 strengthen in case can be positively with operative end 46 this part with vertical light path 88 blockings.Can on these operative end 46 parts, install opaque sponge rubber etc. in case of necessity, can more increase the area of the vertical light path 88 of blocking like this.

On each photodetector 90 in length and breadth, in this example shown in Figure 71, be connected with and detect loop 92, thereby detect the position (coordinate) of the intersection point of the light path 88 that light quantity reduces, also promptly determine the switch portion 314a that is operated so that the signal from each photodetector 90 is responded.But this detection loop 92 also can not be attached to this touch pad 114, but utilizes loop being provided with in the instrument connected or microcomputer etc.

As depress press button 32, and press button 32 enters light path 88, and its operative end 46 of more specifically saying so enters light path 88.At press button 32 when being opaque, light 86 is interdicted fully by it.When press button when being transparent or semitransparent, though light can not be blocked fully, because the refraction of generation, decay etc. in the operative end 46 of press button 32, light quantity can reduce, the signal level of being examined then element 90 outputs by the light of correspondence also can reduce, and has press button to enter so can detect in the light path 88.At press button 32 when being transparent or semitransparent, in order to strengthen effect to the shading or the decay of light 86, the end face blacking that is positioned at the press button 32 of light path 88 can be made it opaque, also this end face can be carried out half-light processing and make light 86 scatterings or carry out mirror finish etc. and make light 86 reflections.Perhaps, because movable side magnetic 52 is not transparent, its position arrangement also can on light path.In addition, as previously mentioned, also opaque sponge rubber etc. can be installed on operative end 46.

＜the 34 embodiment 〉

Figure 75 is for adopting ultrasonic type touch pad, flatly moving type press button and can producing the stroke sense and the part sectioned view of the embodiment of the display panel of the belt switch of the slim switch 80 of keystroke sense.

Slim switch 80 among the embodiment of this Figure 75 have ultrasonic type touch pad 324 and with Figure 15 identical operations portion 30.

This touch pad 324 for example with United States Patent (USP) 5,177, the touch pad of recording and narrating in No. 327 is identical.

The limit portion upper surface place that is included in substrate 94 with reference to the formation of this touch pad 324 of Figure 76 is a plurality of oscillating elements 96 of the output ultrasonic wave US of configuration and receive ultrasonic wave US and convert it to a plurality of oscillation test elements of the signal of telecommunication relatively in length and breadth, and the rectangular ultrasonic route 302 that forms on substrate surface.Just become switch portion 304a near the intersection point of two ultrasonic circuits 302 respectively.In this occasion,, needn't worry usually can enter adjacent ultrasonic circuit 302 and cause interference through the ultrasonic US that a ultrasonic circuit 302 is propagated because the directionality of ultrasonic wave US is high.

Substrate 94 for example can be transparent or semitransparent glass substrate.

Ultrasonic wave US is elastic surface wave in this example, and the ultrasonic wave US that is sent by oscillating element 96 passes through waveguide and the surface of the substrate 94 that leads, and the ultrasonic wave US on substrate 94 surfaces is then through waveguide 304 guiding oscillation test elements 306.

Each oscillating element 96 and each oscillation test element 306 are piezoelectric vibrators for example.

On each the oscillation test element 306 on the direction in length and breadth, in this example shown in Figure 76, be connected with and detect loop 308, thereby detect the position (coordinate) of ultrasonic circuit 302 intersection points of ultrasonic wave US decay, promptly determine the switch portion 324 of being operated so that the signal from each oscillating element 306 is responded.But this detection loop 308 also can not belong to this touch pad 324, but utilizes interior loop that is provided with of the instrument that is connected or microcomputer etc.

In the past being that surface with the substrate 94 of this touch pad 324 such as formation such as the finger contact of etc.ing absorbs ultrasonic wave and makes its decay and operate, as with regard to this situation, is zero owing to there not being moving part to be pressed into its stroke, can't obtain the stroke sense.

In contrast, be to utilize press button depressed to make ultrasonic US decay in the present embodiment.Limit portion at the lower surface of press button 32 is provided with ULTRASONIC ABSORPTION body 310 for this purpose.ULTRASONIC ABSORPTION body 310 is the quite soft ultrasonic object of energy good absorption, as silicon rubber, poly-Xi'an ester rubber etc.This ULTRASONIC ABSORPTION body 310 can be provided with on the part that is positioned at ultrasonic route 302 at least.But the resilient resin of press button 32 employings etc. forms also passable, in the sort of occasion, because press button 32 self can absorb ultrasonic wave and make it decay, ULTRASONIC ABSORPTION body 310 can be set no longer.

In addition, support 36 absorbs ultrasonic wave hardly usually by making such as animi resin, even so it be present in do not have on the ultrasonic circuit 302 yet improper.If improper, it is promptly good otch to be set in the bottom of the support 36 on the ultrasonic circuit 302.

When press button 32 is depressed, ULTRASONIC ABSORPTION body 310 contacts with the ultrasonic circuit 302 on the surface of substrate 94, ultrasonic wave US is absorbed by this ULTRASONIC ABSORPTION body 310 and decays, because the corresponding output signal level that oscillation test element 306 produced reduces and can detect the switch portion 324a that is operated.

Like this, in this slim switch 80, because the stroke sense that can guarantee to depress press button 32, so different with the independent occasion of using of original ultrasonic type touch pad, can obtain clear and definite stroke sense.And on this operating portion 30, as previously mentioned, also can obtain the keystroke sense.

In addition, when the ultrasonic touch plate that utilizes elastic surface wave originally uses separately, as its surface attachment foreign matter (for example worm, dust, water droplet, oil film etc.) is arranged, because ultrasonic meeting is absorbed with the problem that misoperation may take place for it and exists always, but in this slim switch 80, even have foreign matters such as worm, dust, water droplet, oil film to adhere at press button 32, also can therefore not produce misoperation.So reliability height.

Remaining feature is identical with the occasion that adopts resistance membrane type or photoelectric type touch pad.

Also can not use above-mentioned surface acoustic wave as ultrasonic wave US, and replace deformation wave, shown in Figure 77 at substrate 94 internal communications.In this case, the opposing end surface at substrate 94 is provided with oscillating element 96 and oscillation test element 306.This mode also claims the inner face waveguide type.

Under this occasion, when press button 32 being depressed the substrate surface that makes on the ultrasonic circuit of pecking acceptor 310 contact ultrasonic wave US, say more specifically when Billy uses a little with the occasion of surface acoustic wave more and defeat following time that ultrasonic wave US (deformation wave) decay of internal communication just can detect press button 32 and depress.

Also promptly, if press button 32 is a flatly moving type, as previously mentioned, because press button is to tilt to depress, and how to tilt be the position decision of being depressed and there is no certain.So, correspondingly to work hard or the switch portion area is strengthened the choice of location of switch portion 314a, the 324a of touch pad 114,124.Otherwise in each embodiment of rotary type, because press button 32 only rotates, the position of the operative end 46 that the switch portion of touch pad is operated is determined.So the switch portion 314a that is provided with on touch pad 314,324, the position of 324a are also determined.Switch portion 314a, the 324a bottom line that also is touch pad 314,324 is to get final product with giving prominence under 47 in each operative end 46 or operation, its area need not be done too much.＜7. other examples 〉

Magnetization in the＜7-1. face 〉

In the resetting means of aforementioned each embodiment, in the employed permanent magnet, be on the relative two sides of this permanent magnet, to form the N utmost point and the S utmost point.For example with corresponding Figure 86 of Figure 15 embodiment in the upper end face of permanent magnet of movable side magnetic 52 be the N utmost point, rear surface is the S utmost point.In the occasion of this structure, there is magnetic line of force MG to spill around the permanent magnet, below the embodiment that this point is improved, describe.Following embodiment is " magnetization in the face ", and promptly in the face of forming the S utmost point and the N utmost point on the face of magnetic metal, and the thought that does not form magnetic pole on another side is specialized.

Magnetization in the face of permanent magnet in the＜7-1A. flatly moving type 〉

＜the 38 embodiment 〉

Figure 87 is the part sectioned view of an example of the display panel of the belt switch of magnetized permanent magnet in the employing face in resetting means.The part identical or suitable with the embodiment of Figure 86 adopted same symbol, below mainly the embodiment difference with Figure 86 is illustrated.

Resetting means 50A below the display panel of the belt switch of the embodiment of Figure 87 adopts is as the resetting means suitable with the resetting means 50 of the embodiment of Figure 86.

Promptly in this example the formation of resetting means 50A be included in fixation side magnetic 54 that press button 32 is encased and the limit portion that is positioned at press button 32 that the top of the support 36 that uses as guiding elements is provided with and be in said fixing side magnetic 54 below the movable side magnetic 52 that is provided with facing to the fixation side magnetic.The embodiment of fixation side magnetic 54 and Figure 86 is identical to be to be formed by magnetic metal.

On the other hand, movable side magnetic 52 is one has the N utmost point and the S utmost point to exist on a face (being upper surface in) relative with its other side's magnetic metal 54, and in it opposes the face of the no magnetic pole existence of one side (being in the lower surface) magnetized permanent magnet.

Figure 88 illustrates one of the movable side magnetic 52 of this kind example.Movable side magnetic 52 in this example is that four side ring shapes alternately form the N utmost point and the S utmost point on the side face direction thereon.No magnetic pole forms on the lower surface.

Figure 89 illustrates section and the fixation side magnetic 54 of movable side magnetic 52 along Figure 88 center line a-a direction simultaneously, and the distribution of magnetic line of force MG is shown simultaneously.

Movable 52 interior magnetizing methods of side magnetic also can make the upper surface N utmost point and the very concentric shape of S of movable side magnetic 52 shown in Figure 90.

In addition, replace the movable side magnetic 52 of above-mentioned ring-type can use, it is arranged on press button 32 each limit gets final product as magnetized bar-shaped movable side magnetic 52 in illustrative of Figure 91 A or Figure 91 B.At this moment, when this magnetic is arranged at least the work that gets final product is set on the limit.

Utilize above-mentioned resetting means 50A, identical because can produce gravitation to the other side's fixation side magnetic 54 with the situation of the resetting means 50 of the embodiment of Figure 86 as the movable side magnetic 52 of permanent magnet, can apply reset force to press button 32.

And, in this resets means 50A, only be present in the upper surface relative as the N utmost point of the movable side magnetic 52 of permanent magnet and the S utmost point with the other side's fixation side magnetic 54, in lower surface, there is not magnetic pole, therefore the magnetic line of force MG that sends by the N utmost point of movable side magnetic 52, as shown in Figure 89, return and its adjacent S utmost point in one side, perhaps return with the S utmost point in the one side by side magnetic 54 inside that are relatively fixed, so just form little closed loop, thereby different with employing in the situation of the embodiment of the movable side magnetic 52 of the magnetized Figure 86 of thickness direction, the diffusion of magnetic line of force MG in the space can be eased down to minimum.

Particularly in the movable side magnetic 52 attraction the other side fixation side magnetics 54 that are made of permanent magnet, owing to form almost completely closed magnetic circuit by the fixation side magnetic 54 that is attracted, the magnetic line of force does not almost completely spill to the space.So, different with the embodiment of Figure 86 in Figure 87, the magnetic line of force of coming in and going out in the movable side magnetic 52 can not be shown on the figure.

In addition, as mentioned above, the magnetic line of force is very little in spatial diffusion, the suction of the complete 52 pairs of the other side's fixation side magnetics 54 of the movable side magnetic of result is just very big, so can correspondingly reduce the magnetization (remanent magnetism) of movable side magnetic 52, interrelating therewith certainly reduces stray field from movable side magnetic 52, and this also helps to reduce stray field.

By above-mentioned effect, can be reduced to the stray field of operating portion 30 very little.So, for the display panel of this belt switch, though with magnetic recording mediums such as magnetic card take near it, also needn't worry the record of this magnetic recording medium can be confounded.

And in this resetting means 50A, the thickness of fixation side magnetic 54 need not be done especially bigly, so the thickness of the display panel integral body of belt switch can be little.

Magnetization in the face of the permanent magnet the in＜7-1B. rotary type 〉

＜the 39 embodiment 〉

Embodiment shown in Figure 92 be with the display unit of the belt switch of the similar rotary type of embodiment of the rotary type of aforementioned Figure 28 in, permanent magnet magnetized embodiment in the employing face in press button 32.In addition, Figure 93 is the plane graph of the press button among Figure 92.Below, be that the center describes with difference with the embodiment of the embodiment of Figure 28 and Figure 87.

Near the end that employed resetting means 50A is the fulcrum that is arranged at press button 32 with outstanding 45 offside among the embodiment of Figure 92, promptly with the limit portion of aforesaid operations end 46 homonymies near.The fulcrum that this resetting means 50A comprises the fixation side magnetic 54 on the top that is arranged at support 36 and is positioned at press button 32 is with the end of the offside of projection 45 and be in the below of this fixation side magnetic 54 and the movable side magnetic 54 that is oppositely arranged with fixation side magnetic 54.

Movable side magnetic 52 is one has the N utmost point and the S utmost point to exist on a face (being upper surface in) relative with its other side's fixation side magnetic 54, and permanent magnet magnetized in it opposes the face of the upward no magnetic pole existence of side one side (being in the lower surface).Magnetization is identical with Figure 91 A or Figure 91 B example in the face of this movable side magnetic 52.

Figure 93 illustrates an example of the planar configuration of movable side magnetic 52.This movable side magnetic 52 can be as shown in this example, is arranged in the whole limit portion of fulcrum with the offside of projection 45, also can be arranged on the part of this limit near central authorities, perhaps can be arranged at the place, two ends of this limit portion.Adopt which kind of mode will depend on that gravitation between this movable side magnetic 52 and the fixed value magnetic 54 etc. decides.But,, its other side's fixation side magnetic 54 is set above this movable side magnetic 52 all no matter in which kind of occasion.

Also identical with the embodiment of Figure 87 almost of the structure of resetting means 50A in the present embodiment, so it is identical with the occasion of the embodiment of Figure 87, it is very little that the stray field of operating portion 30 can be reduced to, and can reach the less effect of integral thickness of the display panel that makes belt switch.

＜7-1C. uses the variation of magnetization occasion in the face 〉

In the various embodiments described above, when fixation side magnetic 54 also is the occasion of utilizing permanent magnet to produce, requirement is carried out on the one side (being lower surface) relative with movable side magnetic 52 magnetizing in the face that the N utmost point and the S utmost point alternately exist in these fixation side magnetic 54 upper and lower surfaces, and does not exist at its another side (being upper surface) internal magnetic pole.In this occasion, the arrangement of each magnetic pole of magnetized movable side magnetic 52 is just in time relative with the opposite polarity magnetic pole of fixation side magnetic 54 in the face.For example, the upper surface at movable side magnetic 52 is N along circumferential direction, S, N ... when magnetizing in the face of formula, then the lower surface of fixation side magnetic 54 is S along circumferential direction, N, S ' ... magnetization in the face of formula.The combination of magnetized fixation side magnetic 54 in the movable side magnetic 52 of the A of Figure 91 shown in Figure 94 and corresponding with it face.

Like this, if fixation side magnetic 54 and 52 liang of aspects of movable side magnetic all are mutually in opposite polarity during magnetized permanent magnet, its gravitation is than the occasion height that has a side for simple (promptly unmagnetized) magnetic, so reset force of resetting means 50A, needed pressing force when in other words pushing switch portion 4a that press button 32 makes touch pad 4 and connecting also can improve.And, gravitation not high also can the time, just can reduce the magnetization (remanent magnetism) of fixation side magnetic 54 and movable side magnetic 52, the stray field of relevant certain two magnetics 54,52 also can reduce therewith, and the stray field of operating portion 30 also can further reduce.

＜7-2. magnetic utilizes 〉

＜the 40 embodiment 〉

What use in the various embodiments described above all is the permanent magnet that the magnetization of the magnetic material of bulk is formed.For example, in the example of Figure 86, what use as fixation side magnetic 54 is iron plate, and what use as movable side magnetic 52 is block permanent magnet 44.So, stopping to depress in press button 32 back press buttons reset, promptly movable side magnetic 52 attract fixation side magnetics 54 metallic plate 52 both can send bigger one " noise made in coughing or vomiting " when directly contacting.Even having has this sound to send also not have any relation in a lot of purposes, but the occasion of not wishing to take place this sound is also arranged, as machine used in the studio, broadcasting station etc.

Sound in order to reduce to reset is also considered between fixation side magnetic 54 and movable side magnetic 52 every with the such intermediary's elastomeric material of rubber, but that is will increase number of parts and assembler the time and raise the cost.

So the sound when resetting in order to reduce press button preferably is used in the resin magnetic system work of sneaking into magnetic in the resin with fixation side magnetic 54 in the various embodiments described above and movable side magnetic 52.The typical case of this resin is various nylon.The most handy ferromagnetism metal of magnetic is made, as various ferrites.This resin magnetic body can be shaped when making, and processability is good.In addition, after the making, shown in Figure 88, Figure 89, Figure 90, Figure 91 A, each example of Figure 91 B, Figure 94, be easy to carry out magnetizing in the face.

Like this, two sides' magnetic 52 and 54 as all use the resin magnetic body, then two magnetics 54 and 52 attract each other and when directly contacting, the resin that constitutes them can be with impact absorption, so the sound that resets can reduce when press button 32 resets.Therefore, studio, broadcasting station etc. like that to the purposes that the strictness of sound condition takes place in the display panel of this belt switch also can use without a doubt.And because the situation of the intermediary elastomeric material such with increasing rubber is different, the number of parts assembling can not increase man-hour, the problem that does not exist cost to improve.

In addition, using the resin magnetic system to make the occasion of fixation side magnetic 54, it and support 36 can used all that the resin magnetic body is integrated to be made.In this occasion, magnetization makes it to become permanent magnet in the face as fixation side magnetic 54 is carried out, as long as magnetize the necessary position on movable side magnetic 52.Thisly fixation side magnetic 54 is made the occasion that is assembled into the fixation side magnetic again with the method for support 36 integrated manufacturings respectively with both compare, the assembling meeting of the display panel of operating portion 30 and belt switch is more simple.

In addition, when as Figure 86 embodiment, using iron plate to use fixation side magnetic 54 as, even its surface is through electroplating or japanning, but unavoidably have pin hole on it, so can get rusty easily to make and electroplate and the coat of paint peels off along with time iron plate, so just may make the outward appearance deterioration quality decline of the display panel of this belt switch.

In contrast, when if the fixation side magnetic 54 in the various embodiments described above is made magnetic with resin magnetic system work and with ferrite, can avoid the fixation side magnetic to get rusty, the japanning that its result then can suppress the surface of fixation side magnetic 54 is peeled off, and therefore can keep good surface appearance for a long time.Its reason is that ferrite is with MFe ₂O ₄The oxide magnetic compact of the structural formula representative that (M is the divalent metal) is such is oxidation-stabilized state originally, is difficult to reoxidize, and promptly is difficult to corrosion.

The typical case of this ferrite is nickel ferrite based magnetic loaded, nickel ferrite based magnetic loaded cobalt, ferrous acid manganese magnesium etc., but and more than these.

In the occasion that constitutes movable side magnetic with the resin magnetic body, whether this magnetic uses the ferrite can be careless, but the resin magnetic body constituent ratio less expensive of fixation side magnetic 54 and movable side magnetic 52 usefulness same materials.
